TRUST · DISCLAIMERS

Disclaimers

One job: state what How To Calculate tools are and are not. Calculators are educational planning sketches. They do not replace licensed advice, filings, underwriting, or clinical care.

Framing: YMYL scope lanes with a before-you-rely checklist, not an emoji warning farm and not a Terms of Use reprint.

Before you rely on a result

  1. 01Read the formula, assumptions, and limitations on that calculator page.
  2. 02Treat the output as a sketch, not a contract, diagnosis, or filing.
  3. 03Confirm critical numbers with a qualified professional or official form.
  4. 04Report material formula or unit errors via Contact with the page URL.
